To all fro/0m 'it may concer/12 Be it known that ldaoon lt/lnnwirz, a citizen of the lUnited States7 residing in North Troy, New York, have invented ll/later-Wlotors, of which the following is a specification.

@ne object of my invention is to provide a simple1 compact and substantial form of water motor whose parts shall be so disposed that it shall not be likely to get out of order or require repairs for long periods of time g-the construction and arrangement being such as to allow of a short and direct flow of water from a pressure chamber to the cylinders and from the latter to the exhaust chamber.

l further desire to provide a water motor which shall include a novel arrangement of pressure and exhaust chambers, together with a relatively simple form of valve mechanism for controlling the flow of liquid between said chambers and the cylinder.

These objects and other advantageous ends l attain as hereinafter set forth, reference being had to the accompanying drawings, in which,

Figure 1 is a side elevation of a water inotor constructed in accordance with my invention;

Fig. 2 is a horizontal section on the line 2-2, Fig. 1; and l Fig. 3 is an enlarged vertical section on the line 3--3, Fig. l.

Referring to the above drawings7 1 represents a horizontally elongated hollow base structure divided by a longitudinally extending partition 2 into two chambers 3 and 4 of which the first is supplied through a bottom inlet 6 with water under pressure while the latter is similarly provided with two outlets 5-5 also in its lowest or bottom part, through which the water exhausted from the apparatus may escape.

Mounted on the base structure 1 is a series of vertical cylinders 7 having any desired construction but in the present instance illustrated as made in the form of a single casting. The bottom of each of the cylinders is connected to the pressure chamber 3 through a valve seated opening closed by a downwardly opening valve 8 and each cylinder likewise communicates with the exhaust chamber a through a second valve seated opening in which is operative an up- Speccaton of Letters Patent.

ends provide bearings for a main shaft 15 extending at right angles to the center lines of the cylinders and having a crank 16 over each of them connected to the adjacent piston or plunger 10 by a rod 17.

Each of the valves 8 is rigidly attached to a vertically slidable block 18 guided in grooves in the side walls of the pressure chamber 3 and having an opening for the reception of a cam 19 fixed to a shaft 20 extending longitudinally through said chamber and projecting outside of the ends thereof. This shaft is driven through suitable gearing 21 from the main shaft 15 and has fixed to that one of its ends distant from said gearing a pinion 22 meshing with a second pinion 23 fixed on a shaft 24 which extends through the exhaust chamber f1. Both of these shafts are mounted in suitable bearings in the base structure 1 and are preferably provided with stung boxes where they.

pass through the walls of said chamber, in order to prevent leakage of the liquid therein. with a number of cams 25 operative respectively within the openings of the slides 26. The latter, as in the case of the slides 18, are guided in vertical grooves formed in the walls of the exhaust chamber and are operatively connected to the exhaust valves 9 which are normally hel d seated by springs 27.

rJhe various cams or eccentrics 19 are so mounted on the shaft 2O as to successively open the valves 8, in each instance when the piston of the adjacent cylinder is at the lower part of its stroke. Likewise the cams 25 are so placed as to successively open the valves 9 and thereby permit the exhaust of water from the cylinders when the pistons or plungers 10 have been moved to the outer or upper ends of their respective cylinders. lWhile the cranks 16 may be arranged in any desired relative positions, l'. have illusrlfhis second shaft is similarly provided l trated them as each set 90 in advance of the crank to one side of it and 90 behind the crank on the other side.

With the above described arrangement of parts, some one of the valves 8 is open at any given time so that if Water under pressure be admitted to the pressure chamber 3 through the inlet pipe 6, the motor Will start, owing to the flow of Water from said chamber into at least one of said cylinders and the resulting upward movement of the piston or plunger 10 therein. lf the cams or eccentrics on the shafts 20 and 2d be properly timed, the valve 8 of the second cylinder will be opened before the first plunger reaches the top of the cylinder, after Which the exhaust valve 9 of said first cylinder will be opened, permitting the escape of the Water therein just as the first piston reaches the top or upper end of its stroke. The four pistons in the motor illustrated are thus successively actuated and caused to act upon 4the main shaft 15 Which is thus continuously rotated,-motion being' transmitted from it to the gearing 2l through the shaft 20 and thence through the gears 22 and 23 to the second shaft 24.

-From the above description it Will be noted that I have provided a relatively direct path of flow for the Water under pressure as it passes from the inlet pipe 6 through the chamber 3 to the various cylinders 7. Likewise the Water exhausted from the cylinders is permitted to iloW in short direct lines therefrom through the chamber el to the Waste pipe 5 in the bottom thereof.

l claim:

'lhe combination in a Water motor, of a base structure, a longitudinal partition therein dividing the same into a pressure and an exhaust chamber; an intake and an exhaust for said chambers respectively; plunger cylinders mounted on said base and communicating with the chambers through valved openings; oppositely operated valves controlling said openings; reciprocating slides operable in grooves in the chambers, each of said slides being connected with one of said valves; two intergeared shafts longitudinally disposed in said chambers; cams on said shafts adapted to engage the slides and impart movement thereto in predetermined sequence; plungers in the cylinders; a crank shaft actuated by said plungers; and means for driving the cam shafts from said crank shaft.

In Witness whereof I afix my signature.

JACOB MERWITZ.
